Navigating with Stars Saturday, June 12, 2021 9:00 PM For centuries, navigators have relied on stars to identify directions, compute latitude, and even read local time. We will explore these ideas and examine the problem of measuring one’s longitude at sea – a fascinating problem that defeated some of the best minds in the world for many years.
